La parola e le sue rappresentazioni: nota sul Maḵzan al-asrār di Neẓāmi Ganjavi

In the light of several previous studies, this contribution aims to introduce the study of Neẓāmi’s poetics through the reading of his poems but specifically through the verses dedicated to his reflection on the soḵan. In this first essay, we start from the reading and analysis of two chapters from Maḵzan al-asrār explicitly dedicated to this subject. The paper proposes a brief introduction to place the two chapters in their more general context, the translation of the 93 verses and a brief thematic and rhetorical analysis of their development, which represents the theoretical-aesthetic premise for all his later works

AVALIAÇÃO EXPERIMENTAL DO COEFICIENTE DE TRANSFERÊNCIA DE CALOR POR CONVECÇÃO EM CILINDROS E GEOMETRIAS NÃO CILÍNDRICAS

No cenário atual as mais variadas formas de transferência de calor sãoestudadas para uma otimização dos processos industriais envolvidos. Tal otimização se faz presente em épocas onde a energia térmica é extremamente primordial, onde o aumento da eficiência dos processos que envolvem transferência de calor deve ser priorizado. Dentro da área envolvendo energia térmica, tem-se o coeficiente transferência de calor por convecção, o qual determina a intensidade do fenômeno de transferência de calor entre uma superfície e um fluido. O objetivo deste trabalho é a avaliação do coeficiente de convecção h, em geometrias cilíndricas e não cilíndricas. Este consiste na montagem de uma bancada experimental utilizando convecção forçada, que através das correlações empíricas disponíveis na literatura, seja possível determinar o valor do coeficiente de convecção h. Para a determinação do coeficiente convectivo relaciona-se as correlações empíricas apresentadas na literatura. Os experimentos foram conduzidos no laboratório de Ciências Térmicas da UNOESC, onde se utilizou uma bancada equipada com medidores de temperatura e velocidade do ar. Para que aconvecção forçada pudesse ser controlada, utilizou-se um ventilador axial com inversor de frequência, o que permitiu a obtenção de uma gama de valores de números de Reynolds. Posteriormente realizaram-se simulações do experimento em software comercial, com a finalidade de realizar uma comparação dos resultados encontrados experimentalmente. Os resultados encontrados apresentaram boa concordância com a literatura

Natural attenuation can lead to environmental resilience in mine environment

Four streams flowing in the Iglesiente and Arburese mine districts (SW Sardinia, Italy), exploited for zinc (Zn) and lead (Pb) extraction from sulphides and secondary non-sulphide mineralization (calamine ores), have been studied combining investigations from the macroscale (hydrologic tracer techniques) to the microscale (X-ray powder diffraction, scanning electron microscopy, X-ray absorption spectroscopy). In the investigated area, concerns arise from release of metals to water during weathering of ore minerals and mine-waste. Specifically, Zn is observed at extremely high concentrations (10s of mg/L or more) in waters in some of the investigated catchments. The results from synoptic sampling campaigns showed marked differences of Zn loads, from 6.3 kg/day (Rio San Giorgio) to 2000 kg/day (Rio Irvi). Moreover, natural attenuation of metals was found to occur i) through precipitation of Fe compounds (Fe oxy/hydroxides and “green rust”), ii) by means of the authigenic formation of metal sulphides promoted by microbial sulphate reduction, iii) by metal intake in roots and stems of plants (Phragmites australis and Juncus acutus) and by immobilization in the rhizosphere, and iv) by cyanobacterial biomineralization processes that lead to formation of Zn-rich phases (hydrozincite and amorphous Zn-silicate). The biologically mediated natural processes that lead to significant abatement and/or reduction of metal loads, are the response of environmental systems to perturbations caused from mine activities, and can be considered part of the resilience of the system itself. The aim of this study is to understand the effect of these processes on the evolution of the studied systems towards more stable and, likely, resilient conditions, e.g. by limiting metal mobility and favouring the improvement of the overall quality of water. The understanding of how ecosystems adapt and respond to contamination, and which chemical and physical factors control these natural biogeochemical barriers, can help to plan effective remediation actions

Understanding Others' Regret: A fMRI Study

Previous studies showed that the understanding of others' basic emotional experiences is based on a “resonant” mechanism, i.e., on the reactivation, in the observer's brain, of the cerebral areas associated with those experiences. The present study aimed to investigate whether the same neural mechanism is activated both when experiencing and attending complex, cognitively-generated, emotions. A gambling task and functional-Magnetic-Resonance-Imaging (fMRI) were used to test this hypothesis using regret, the negative cognitively-based emotion resulting from an unfavorable counterfactual comparison between the outcomes of chosen and discarded options. Do the same brain structures that mediate the experience of regret become active in the observation of situations eliciting regret in another individual? Here we show that observing the regretful outcomes of someone else's choices activates the same regions that are activated during a first-person experience of regret, i.e. the ventromedial prefrontal cortex, anterior cingulate cortex and hippocampus. These results extend the possible role of a mirror-like mechanism beyond basic emotions
